Jetson AGX Xavier with SJA1105Q issue

Hi , nvidia experts,
My board connection is
and my linux kernel driver is Jetpack 4.6.1 with 5.0.2 nvethernet driver(i.e. porting Jetpack 5.0.2 nvethernet driver to 4.6.1).
I followed the suggestion in the forum
and configure xavier nvethernet to be 1000FD fixed link and for most of time it works fine but sometimes it doesnot work and I checked the eth0 and it shows the TX is fine and the RX is not.
and I checked eth0 with ethtools and it showed there is no RX error in ethtool.
When eth0 is bad, the other two ethernet connection between TDA4VM and phy is OK.
Here is my dmesg (976.1 KB)

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.

Why you do that? Is JetPack 5.0.2 just working without problem?
